Possibly yes, now my QNAP doesn't have services that absolutely need to be up 24/7. OTOH my free time is extremely limited, but with instructions and kernels available I can see if I can find time. I should have 3.3V TTL to RS-232 wires somewhere that I used with TS-109, and although https://www.cyrius.com/debian/kirkwood/qnap/ts-219/serial/ doesn't explicitly list TS-221, maybe I can trial and error until I find the correct pins. -Timo
